for supporting and n'ianipulating such lengths duri g the fasteningoperation.

In the various Ways in which tubes of cardboard or other penetrable material are employed, for instance. cores for rolls of paper it has been found eripedientto build up a tubular length from shorter lengths placed end to end and an object of the present invention is to provide means for mechanically fastening together tubular lengths in end to end relation. Another objectis to incorporate in such machine means wherebythe tubular lengths are fastened circun erentially of their adjacent ends. Another object is to provide an automatic stop for discontinuing the operation of the machine upon the completion of a prescribed cycle of operations.

My invention specifically features iniproved stapling mechanism adapted for stapling adjacent ends of the compound cores or spools upon which roll paper is Wound as it passes from a' paper making machine, combined with mechanism for supporting and manipulating the tubular lengths in such manner that they are solidly supported during the stapling operation and intermittently freed for mechanical or auto matic rotation to the e d that successive staples are arranged circui'i'iferentially of the core. m'ovision being made for the an toniatic stoppage of the machine upon the completion of the piastening operation and rotation of the core.

The above objects and features with others will be hereinafter more fully described and particularly pointed out-in the append ed c aims.

For full roinprehension however, of my Fig. l.

the pedestal 3 invention-.reference shouljd be had to the accompanying drawings forming a part of this specification, in which the same reference characters indicate like parts and wherein: i

Fig. 1 is aside. elevation of the tubular length fastening machine; I

Fig. 2 is a plan view thereof;

is an end elevation; Fig. lis an enlargeddetail side elevation of the st pling head with thefrontcover plate removed; and I .Fig. 51s a vert cal section on line 55 Referring now to the drawings, 2 indicates a bed plate at the opposite ends of which are respectively located a pedestal 3 and a post l the latter having strapped thereto at 5 one end-of a cylindrical bars6' constituting a support for tubular cores and extending; freely towards and in front of referably above the top level of the latteigbeneath and just'beyond the staplinghead or other "fastener supplyingdevice ofthe machine which will he hereinafter described.

The cores 7 to be fastened are received upon the free end of support 6, encircling the latter and positioned Withftheir abut-- ting endsbeneath the head ofthe fastening lffleCllillllSIIl Which is driven by a ho'rizontal shaft 8 extending between and bearingin the lower portions of'the legs of pedestal ,3, this shaft being driven by a counter-shaft 9 at the side of and extending rearwardly of the pedestal and supported at its front end in a bearing 10 extendinglaterally from the pedestal and at its rear end in a bearing 11 upon a rearward extension 12 of the bed plate. An operative connection is established between the shafts 8 and '9 by gears and 14 respectively carried by the shafts, the counter shaft receiving power from a suitablevsource through loose pulley 15 combined with a clutch 16' With clutch lever 17 fulcruined upon the bed plate extension and connected by a rod 18 to a starting treadle 19 located at the front of the pedestal. r

The fastening mechanism is operated by an eccentric disc 20 upon shaft 8, a cou Y ing rod 21 being strapped to the eccentric,

extending upwardly and being connected to ting lengths are turned to present a fresh location for the reception of the succeeding fastening. Such rotating means consists preferably of an eccentric disc '22 upon a forwardextension of shaft 8 outside the pedestal, such eccentric being connected by an upwardly extending connecting rod 23 to the lowerend of a verticalbplu mounted within a guide 2 i upon the support 6. The upper end of the pin; 7 2e has mounted thereon a dog of berlcrank forin pivoted to the plunger and disposed transversely thereof and of the sup port 6. A spring 26 connected at one end to the plunger and at its opposite end to the inner arm of the dog serves to yieldingly maintain the outer arm of the dog in an outwardly and upwardly extended position with its pointed outer end beneath the support 6, and core thereon so that with each revolution of shaft 8 the consequent vertical reciprocation of the plunger causes the dog to ride upwardly over the core, engage therewith and on the downward stroke of the plunger turn the core through a partial rotation. The outer end of the dog is hooked and carried by the upward stroke of the plunger preferably to a point above the transverse centre line of the support 6, the spring 26 ensuring engagement of the dog with the core. Furthermore the plunger is adapted to intermittently uphold the free end of the support 6 and for this purpose is of a length to engage at the end of the upward stroke beneath the core, it being preferred toform said plunger with a concave head 27 capable of snugly fittino about the underside of the core the head being adjustably mounted by means of a nut 28 for varying the length of the plunger to suit varying core thicknesses or to meet other re quirements of a similar nature.

The eccentrics 20 and 22 are arranged to produce opposed movements upon their respectively actuated members, being disposed on diametrically opposite sides of the shaft so as to effect a downward fastener inserting movement of the fastening mechanism coincidently with an upward movement of the plunger. In this way the core is turned in the periods betweensucceeding fastener inserting operations and the free end of the of the drive shaft and throw out the clutch,

support of rod 6 effectively bracing the core support when necessary and by the lowering of the head 27, clearing such support of obstruction in readinessfor the application of core lengths thereto.

It is preferred to stop the operatio of the machine after each operation of his fastener and turning of the core, these operations being effected during each revolution'of the drive shaft 8 and for this pnrpose said shaft is extended rearwardly at 29 to a rear bearing 30 and carries a radial kicker arm 31 projecting from the slit with its outer end in the path of clutch block 32 carried by clutchring 33, the lzicl; r being adapted to strike the block each revolution a spring controlled brake band 3% e; a brake drum 35 upon extension 29 o suaft ti and stopping the latter immediate It prefer to fasten the core is means of wire staples inserted l ly ot the ad scentlengths and spanning jOliit.

t c F or this purpose the hereinbcfore mentioned fastening mechanisu'i is etieiupln tied in a staple forming and drivir machine of novel construction designed for simplicity and adjustability for use in conjunction with the manipulating mechanism described above.

As will be seen particularly in Figs. i and 5, my stapling mechanism consists r hes d frame mounted upon pedestal E} slidably carrying a vertically disposed 37 passing downwardly thron t-- b he top of the pedestal connected its lower end to the connecting rod 21 and car r upper end above frame 36, a forwardly e5;- tending beam 38; The staple forming and driving mechanism is carried by beam 38 in conjunction with a bracketcxtcnding outwardly from the head the outer Jame 0) end of such bracket being to l cal in which the former a anvil ll is located con ally of the slot and at the bottom thereof, being carried or formed upon the bottom of a vertically (iii-r posed lever tl fulcruincd at centre upon a horizontally disposed pivot extent. transversely of and carried by the bra 39, the lever being controlled li y a SD! n tending to swing the lever horizon; .o withdraw the anvil rearwardy from its operative position projecting through an aperture at of housing 35) into the slot 40 of the latter. The staple former consists of a slide 45 in sliding engagement with the edges of the slot, and having a matrix at its lower end constituted by an upwardly extending U-form opening of suitable dimensions to pass snugly over anvil 4:1 and is pro panel at? constitutes the driver for inserti. w the staple and is conne arin L8 respectively,

The displaceable connection consists .P1Oi81 ably ct arlatch 51 pivoted at its upper end ing pro ection or pin upon the lower end of the latch 18 adapted to be engaged by a stationary part, for instance the housing 39, when the 'lforn'iei" has been carried down to form the stap l rsuch engagement swinging the latch out from the former 4-5 und dieconnecting it fronrthe connecting arm 48.

otlrousin-g 39, thr ugh an apertured wire block 65 upon the extension, along the grooved top of a cutter 66, transversely across the slot 40 above aperture 4% and anvil 41. 'The cutter 66 is carried by the extensionti l near the lowerend of slot 40 withits inner end just within thela'ter and itsupper inner edge just above the top level of anvil tl constituting a shear cooperating with the adjacent leg of the former to sever the requisite length of the wire in tllGifOITflfltion of the staple. A set screw 67 provides means for moving the cutter longitudinally to adjust its position with respect to the slot l0, A spring pressed idler 68 holds the wire in engagement with feed roll 63, the latter being intermittently rotated to feed the wire forward by means of a spring con trolled pawl (39 depending from an arm 70 extending. laterally from beam 38 the pawl engaging the teeth of a ratchet 71 upon the trunnion of the feed roll. The downward movement of beam 38 causes the pawl to ride over the ratchet to a position in readi ness to engage one of the teeth and rotate the roll during the upward movement ot the beam, a stop 72 limiting the downward travel of the pawl and a pin and slot connection 73 between arm 70 and the pawl accommodating continued movement of the arm.

With reference to'the foregoing descrip tion, the operation of my improved fastening machine is briefly as follows:

Two core lengths are passed over rod 6 with their abutting ends beneath anvil t1 and the machine started by pressure upon treadle 19, the eccentric 2O functioning to .drive the staple formerdownwardly, sever the wire and form the staple, the nose 58 of anvil lever ll then projecting into aperture 57 to withdraw the anvil and the latch 51 engaging cam 56 former which remains the driver 4.? continues lownwards and drives the staple into the abutting ends of the core lengths across the joint the ends of the staple being clinched against bar 6. Meanwhile the eccentric 29. moves head 52? up into engagement with the core lengths to adequately support the bar ti'against the driving strain and to engage dog 25 with the core. The eccentrics then act to raise the staple former and driver and lower the stationary While head 27 thus resetting the staple mechanism ready for theformation and driving of a succeeding staple, causing the pawl. 69 to rise and rotate roll 63 to feed the wire forward and drawing the dog 25 down to turn the joined core lengths whereby a new loca tion, for the succeeding staple so presented ;and spaced from the first circumferentially of the core. The kicker 31 is timed to throw out the clutch at thistime, the disconnected drive shaft being stopped by brake 34C.

The above described cycle is continued until the joined core lengths have been turned through one revolution and staples placed at intervals circumferentially thereof, the composite core being built up by placing additional core lengths upon bar 6 and fastening them as above described to the adjacent ends of the preceeding lengths until the desired length is obtained.
